ing material as-in inking rollers for print- 1ng machines, an object of this invention bee. a: simple and inexpensive means for securing the yielding material to a spindle which forms the shaft of the roller. p

To this and other ends, the invention conslsts of certain parts and combinations of parts, all of Wh1Ch will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings i 1 Figure 1' is anend view ofa roller constructed in accordance with tlllSi'illVGIltlOl'l Fig. 2'is alongitudinal sectioitthrough the roller; W v

Fig. 3 is a perspective view of one of the retaining plates;

Fi 4 is a perspective view of one of the yielding disks of which the roller is made;

Fig. 5 shows an end view of one of the retaining plates, being-secured to the spindle or shaft;and

Fig. 6 is a sectional view of one end of the roller, showing one of the retaining plates being fitted in place.

' Imthe illustrated embodiment of the invention the roller comprises a spindle or shaft. -1 surrounded preferably in the formof disks2 of felt by yielding material,

lying in abutting relation between two retaimng plates 3. A feature of this invention is the securin of these retaining plates to the spindle. his is elfected by providing each retaining plate 3 with a central 0 ening 4, from which leads a slot 5 exten ing to one edge of the plate, the inner end of the slot being narrower than the diameter of the central openin ,4. Near each end the spindle or shaft 1 1s provlded wlth two an- Speoiflcation of Letters Patent.

with two pairs Patented Nov. 12, 1918.

and this application filed February nular grooves 6 and 7, the diameter of the spindle at the groove 6 being substantially equal in width to the inner end of the slot 5,,whereas the spindle at the groove 7 has a diameter substantialy equal to the diameter of the central opening 4..

'By this arran ement it is possible to quickly attach t e yielding material or working surface of the roller to the spindle. The yielding material is compressible in the direction of the length of the roller, thus permitting each of the plates to be fitted or removed from the shaft. In fitting a retaining plate to the spindle the latter is shifted in its plane to cause the portion of the spindle at the groove 6 to travel in the slot 5 until the central opening 4 is reached, when the material expands upon being released and forces the plate 3 laterally into the groove 7. Removal of the plate is effected by compressing the material 2 so that the plate may enter the groove 6, after which the plate may be withdrawn from the spindle by way of the passage or slot 5. It will thus be seen that interlocking connections between the plates and the spindle are provided, making the provision of separate fastening devices unnecessary. While the invention is stated as being used as an inking roller it is apparent that it may be used in other rollers.

The present application is a division of an application filed by me on February 15, 1917, Serial No. 148,781.

What I claim as my invention and desire to secure bv Letters Patent is 1. A roller comprising a spindle provided of proximate grooves, each pair having one of its members deeper than the other, the deeper groove being removed farther from the adjacent end of the spindlethe opening so that the retaining member.

may be fitted over the spindle at theaieener groove and then be moved-laterally of its I lane to bring the opening over-the portion of the spindle at the shallow groove, and

yielding material surrounding the spindle etween the two retaining members.

2. A roller comprising a spindle, two re embers having interlocking con taining m nection W1 h the spindle, and yielding mate- .yielding material plate for the yielding material held in'interlocking connection with the spindle by the I yielding material. Y
